This invention relates to new and useful improvements in sound posts for musical instruments and has for the primary object, the provision of a device of the above stated character which will improve the tone of a musical instrument over the ordinary type of wooden sound posts by clarifying the tone with an increased volume-carrying power and also render the instrument more easily 1 played.

Another object of this invention is the provision of a sound post for musical instruments of the above stated character which will be simple, durable and eficient and which may be manufactured and sold at a comparatively low cost.

With these and other objects in View as will become more apparent as the description proceeds, the invention consists in certain novel features of construction, combina tion and arrangement of parts as will be hereinafter more fully described and claimed.

For a complete understanding of our invention reference is to be had to the following description and accompanying drawings,

in which:

Figure 1 is a sectional view illustrating a musical instrument with the sound post applied thereto and constructed in accordance with our invention.

Figure 2 is a side elevation illustrating the sound post.

Figure 3 is a vertical sectional view illustrating the same.

Referring in detail to the drawings, the numeral 1 indicates a sound post constructed in accordance with our invention and is adapted to be positioned between the sound boards 2 of a violin 3 or any other similar stringed musical instrument. The post 1 is positioned adjacent to the bridge 4 that supports the strings 5 of the instrument and is to clarify the tone and provide greater volume and carrying capacity to the instrument. The soundpost 1 includes a tubular member 6 constructed from aluminum or any other metal suitable for the purpose and is provided with a bore 7 provided at each end with a flared portion 8 to receive the tapered 59 ends 9 of wooden plugs 10, the diameters of which are equal to the diameter of the sleeve 6 and engage the sound boards 2 of the musical instrument as shown in Figure 1. Extensions 11 are formed on the ends of the tapered portions 9 of the plugs 10 and extend into Serial No. 449,278.

the bore 7 as shown in Figure 3.

With the device applied to a violin or other string instrument with the plugs 10 engaging the sound boards will clarify the tones of the instrument and provide a greater volume and carrying capacity to the tones.

lVhile we have shown and described the preferred embodiment of our invention, it will be understood that minor changes in construction, combination and arrangement of parts may be made without departing from the spirit and scope of the invention as claimed.

Having thus described our invention, what we claim is:

boards of a stringed instrument.

2. A sound post for stringed musical instruments comprising a metallic sleeve having a bore with the ends thereof flared, plugs of different material from the sleeve engaging the ends of said sleeve, and tapering portions on the plugs and frictionally engaging the walls of the flared portions of the sleeve.
